Comparison of Tear Film Break-up Time with Schirmer’s Test with Anesthesia to Detect Tear Film Abnormality in Patients with Pterygium - A Study from Jammu and Kashmir
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2017, Vol 5, Issue 3
Abstract
Background: Pterygium appears as a triangular fold of vascularized conjuctiva, the apex lies towards the cornea and base merges with the sub-conjunctival tissue. Generally, it is asymptomatic but may cause redness, lacrimation, photophobia, foreign body sensation (dry eye symptoms) and astigmatism. Objective: To compare tear film break-up time test with Schirmer’s test with anaesthesia in patients having pterygium. Materials & Methodology: The study was conducted at postgraduate upgraded department of Ophthalmology of GMC Jammu over period of one year. 90 patients having unilateral primary pterygium presenting to the eye OPD of GMC Jammu were included in the study. The eye with pterygium was taken as case and other eye taken as control for comparision. The TBUT, Schirmer’s test with anaesthesia/ SCH-2 were estimated in both eyes in all patients. A TBUT of less than 10 seconds, SCH-2 of less than 6mm, were considered abnormal. Results: Among the pterygium eyes, decreased tear film breakup time of <10 seconds was observed in 43 (47.78%) eyes, while only 19(21.11%) of non- pterygium eyes had TBUT of <10seconds. On the other hand, 22 (24.44%) eyes with pterygium had Schirmer's test with anaesthesia abnormal. Conclusion: To detect tear film abnormality in patients with pterygium tear film break-up time has better diagnostic value as compared to schirmer’s test with anaesthesia.
